Collection consists of audiovisual materials featuring recordings of events given by and used by members of l'Arche International/Internationale. This material includes 1708 audio cassettes, 37 videocassettes, 8 film reels, and 78 audio reels. Much of the material features recordings created at L'Arche retreats internationally, such as the Covenant Retreat, Renewal Retreat, and Faith and Light Retreat. Prominent speakers include Jean Vanier, Henri Nouwen, Joe Egan, Robert Larouche and Sue Mosteller.

The majority of the audio files feature Jean Vanier, usually speaking at retreats. The film reels are recordings made and collected by L'Arche Daybreak, and feature a CBC film on Daybreak (from 1970), pilgramages and trips made by Faith and Light and Daybreak. There is also a film reel of Jean Vanier.
